Specification of Letters PatentA Patented Oct. 7,1913.

Original application filed September 19, 1911, Serial No. 650,209. Divided and this application filed December 9, 1911.

To all whom. @'25 may concer/i Be it known that we, Anvil) 1V. Eennnno. and CARL SToHLBnnG, citizens of the United States, residing at- Jamestown, in the county of Chautauqua and State of New York. have invented certain new and useful Improvements iniSheet-l\letal `Wmdows, of which the following, taken in connection with the no loose stops on the window fran'ieer'sash" and permitting easy access to the interior ot' the tubular stiles andi-cross rails of the window sashgjand/the invention consists in the constrnefion and arrangement ot' the part /a/s shown inl this speciiication and the ae ompaying drawings and pointed out in the claims.

In the drawings, Figure lis au elevation of a window frame with the sash therein. Fig. 2 is a sectional view of the sash and window frame at line X X in Fig. 1, showinv the construction of the frame und sash stile and the pivotal attachment between the two. Fig. 3 is a sectional view ol the montant at line Y Y in Fig. 1 showing its construction. Fig. 4 is a lengthwise sectional 'view of the two sashes at line Z Z and a portion of the cap and sill of the window frame, portions of the glass being broken away.

Like numerals of 'reference reter to eorresponding parts inthe several views.

.The numeral-10 designates a window frame which is preferably made of two pieces ot' sheet metal joined', as shown in Fig. 2, so as to provide easy attachment to the surrounding wall. The face of the vjamb is provided with parallel spaced grooves 11 in the track of the window sashes 12.

The stiles 153 and cross rails 19 and 20 of the window sashes are euch pret'eral'ily made of one piece of sheet. metal in the tubular form and having a lengthwise growse 1-1 on the inner edge for the glass 15. tiullieient. Space 1G is provided arouxnl the, edge ot' the, glass 15 for suitable packing.

'l`he outer edges of the sash stlles lf-i are Lprovidedwith a lengthwise groove 17, the

Serial No. 664,703.

edges of the sheet metal being bent inwardly and toward one another t-o .forni the groove, but the edges are preferably a spaced distance apart to provide easy'access to the interior of the stile and also be lause it is unnecessary for the strength ot the sash that the edges should he joined. 'lhe spaced distance between the inturned edgesI of the sheetmetal in the groove 174 permits the painting or otherwise coating ot the inside of the tubular stiles and cross rails and also prevents the condensation of moisture within saidtubular stiles and cross rails since thealinosphere is permitted to enter the tubular stiles and cross rails through this opening. The condensation ot' moisture within the hollow sheet 'metal Aconstruction is one of its weaknesses since it easily starts rust and the disintegration of the metal. The tubular stiles and cross rails are joined at the corners preferably bywelding` since this gives a rigid construction witho-ut visible joints.

The groove 17 receives therein the lengtln wise channel strip 18, which channel strip 1S extends into the groove 11 on the jamb. '.lhe outer tace ot the sash stile 13 is made to tit closely' upon the face ot` the jalnh and the groove l1 has sullicient. depth to entirely receive the channel. strip 1S so that when the strip 18 is moved into the channel '11 the sash 12 may be turned pivotally within the oppositely facing; -jambs ol.' the frame 10.

The top cross rail 2() ot the upper sash and the bottoni cross rail 1t) of the lower sash are preferably.made with a eontinimnee of the groove 17 to receive therein a projection 17 on the window sill 15) and a similar projection on the cap 20 ot the frame 10, thereby forming1 a close joint 1xetween the uppe' and lower sashcs and the Sill lil and cap 20". i

ln order to insert the. glass 15 in the upper and lower saslles the meeting.;l rails ot' the sashes are each formed in two-tubular parts 2l and 22, eaeh'of which form about one-third of the cross rail so that the two parts may he placed a special distance apart to receive [he glass 15 thereluilzween, as shown in Finn/l. 'l`ho tubular paris 21 and 22 of the meeting rails are constructed precisely the saine ln the upper and lower vsashes except` that they are turned oppositely sothat one forms the top cross rail of the lower sash and the other forms the bottomrail of the upper sash and the two interlap as hereinafter described.

A lengthwise projection Q3 is provided on the out-er edge of tubular part 21. T he sheet metal inner side of part 22 is continued in an angular-lengthwise flange 2liand the cap piece is provided with a lengthwise curved ilange on the edge'to fit over projection Q3 and an angular return bend Hange on the other edge to engage over flange 24 so that the two return bend flanges of the oppositely placed meeting rails interlap and fit closely against. one another, thereby closing the space between the two rails and holding the rails rinly together when the sash are in the closed position.

It is apparent that the glass 15 may be inserted through the slot between the two parts 21 and 22 before the cap 25 is slipped or sprung into place, and that after the said cap is in place it forms a continuation of the groove 14C and the glass may be cemented or otherwise held in placein the sash within said groove, and also that the cap 25 may he easily removed for the replacing of the glass when broken. The part 21 is provided with an opening 3Q and the part 2Q with an opening 3l which admit to the interior of these parts for coating and prevent condensation as hereinbefore described. The tubular openings in parts 21 and 22 connect into the Stiles 13 and crossbar, so that. a continuous opening is provided around the entire sash. This provides a simple andrconvenient sheet metal construction of which all the parts may be drawn in theregular molding drawing machines. l

When a montant Q6 is desired in the sash it is vpreferably formed ot two channel strips 27 turned back to hack with the channels facing oppositely, and cap strips 28 are then slipped over both -the outer edges of the channel strips 27, thereby forming a strong construction-at low cost and one which provides the two outwardly 'facing grooves 29 for the glass 15.

.By this construction the sash yl2 vare free to slide up and down in the window frame 10,-the channel pieces 1S sliding easily and forming a guide within the grooves 11 when the sash are lrce from one another or from the sill 19 or cap 20 ot the traine, the slashes may be turned pivotally upon the pivot bolt 32, ythe construction ot' which pivot bolt is fully described and claimed in the divisional application lhereinbc't'oi'c mentioned.

'.lhe window sill 19' is cut under and drops away troni the sash rail, as shown at RS in` Fig. Ll', so that the drip from the outide ovthe window will always run away and cannot [low back through the joint betwccnthc under edge of the sash rail and the lengthwise projection 17 0n the sill 19.

1. In a sheet metal window, an upper and a lower sash each having a cross rail formed 1 of two tubular parts, each cross'rail having the outer side ot' its outer tubular part at the top thereof curved outwardly to form a projection, the other tubular part having its inner side spaced from the inner side of the other vsaid tubular part to forni a glass receiving space, the outer side of said second named tubular part being extended outwardly and then inwardly to form allang@ which is spaced from the outer side of the second named tubular part, and a cap which has one side engaged over said projection and has `its opposite side formed of U-shape in cross-section to receive the flange of the second named tubular part, the U-shaped sides of thecaps when the cross rails are in meeting position being engaged with each other and with the adjacent outer sides of the second named tubular partsot the cross i rails.`

2. In a sheet metal window, an upper and a lower sash each having a two-part cross rail, each cross rail having the outer side of its outer part. extended outwardly and iii-- wardly to torina flange which 1s spaced from the inner side oi the cross rail, and a cap engaged over said two parts of each of the cross-rails, said caps each having one side thereof foi-ined of Ufshape in 'cross section so to receive saidilanges in Athe space between the legs ot' the ttshaped parts, the adjacent legs of the U-shaped parts contacting when the sashes are closed and the other legs of the U-shaped parts contacting with the adjacentouter sides of the outer parts of the cross rails.
